Issue #4969 has been updated by Yura Sokolov.
Why not put `abbrev.rb` into `lib/wedge`, and then call `require 'wedge/abbrev'` ? I thought it is standard way.

Bug #4969: Subtle issue with require

If I have a library with same name as Ruby standard library in load path (as an example):
lib/abbrev.rb
There is conflict with loading. Ok, I work around:
require 'rbconfig'
# Notice that rubylibdir takes precendence.
LOCATIONS = ::RbConfig::CONFIG.values_at(
'rubylibdir', 'archdir', 'sitelibdir', 'sitearchdir'
)
#
def require_ruby(file)
LOCATIONS.each do |loadpath|
if path = lib_find(loadpath, file)
return path
end
end
raise LoadError, "no such file to load -- #{fname}"
end
private
SUFFIXES = ['.rb', '.rbw', '.so', '.bundle', '.dll', '.sl', '.jar']
# Given a +loadpath+, a file's relative path, +relname+, and
# options hash, determine a matching file exists. Unless +:load+
# option is +true+, this will check for each viable Ruby suffix.
# If a match is found the full path to the file is returned,
# otherwise +nil+.
def lib_find(loadpath, relname)
if SUFFIXES.include?(File.extname(relname))
abspath = File.join(loadpath, relname)
File.exist?(abspath) ? abspath : nil
else
SUFFIXES.each do |ext|
abspath = File.join(loadpath, relname + ext)
return abspath if File.exist?(abspath)
end
end
nil
end
Now I can do:
require 'abbrev'
require_ruby 'abbrev'
And it works fine. But, if I do:
require_ruby 'abbrev'
require 'abbrev'
The second is not loaded because somehow it seems to confuse it for the first in $LOADED_FEATURES.
I realize this is a very subtle issue and not likely to effect most people, but it presents a big problem for some of my work (e.g. wedge gem)
How is Ruby confusing the two? Can it be fixed? Or is there at least a work around?
